ABB CI858K01 (3BSE018135R1) – DriveBus/DDCS Interface Module for AC 800M Drive Integration

The ABB CI858K01 is a CEX-bus communication interface designed for AC 800M controllers to connect ABB drives over DriveBus (DDCS). From my experience, this module is typically chosen when you want fast, noise-immune communication to ACS800/ACS880/DCS800 drives without extra gateways. You might notice that commissioning gets simpler, and drive diagnostics become available directly in the control system—handy when uptime matters.

Key Features

• DriveBus (DDCS) connectivity – Integrates AC 800M controllers with ABB drives for high-speed setpoint, status, and diagnostics exchange.
• Fiber-optic robustness – Optical links help resist EMI in harsh environments; in many cases this reduces nuisance faults compared with copper.
• Tight 800xA/AC 800M integration – Parameters, alarms, and faceplates are typically easier to map, which speeds up commissioning.
• No external power – Powered over the CEX-bus via the terminal base; fewer power supply points to troubleshoot.
• Compact installation – Standard AC 800M module footprint on TB8xx terminal bases for DIN-rail cabinets.
• Diagnostics and status – Clear indication of link and module health to cut time spent on drive communication issues.

Technical Specifications

Application Fields

You’ll typically see the CI858K01 used where precise motor control and reliable diagnostics are required:

• Pulp & paper: coordinated drive sections on paper machines and winders
• Metals: mill stands and coilers needing fast torque feedback
• Chemical & pharmaceuticals: mixers, extruders, process pumps with speed control
• Cement & mining: crushers, conveyors, fans with stable comms in high-EMI areas
• Marine & terminals: winches and hoists where fiber links are favored

Customer feedback, maintenance lead (cement plant): “Swapping to the CI858-based DriveBus cut our nuisance trips. Diagnostics from the drive show up instantly in the control system.”

Advantages & Value

• Lower engineering effort – Native drive objects and standard AC 800M toolchains save time during FAT and on-site commissioning.
• Fewer points of failure – Direct fiber DDCS means fewer gateways and protocol converters to maintain.
• Lifecycle fit – Aligns with ABB’s long-term 800xA/AC 800M roadmap, which in many cases simplifies spares strategy.
• Serviceability – Clear status LEDs and controller diagnostics shorten troubleshooting windows.
• Cost control – When projects need multiple drives per controller, DriveBus usually scales more economically than third-party links.

Installation & Maintenance

• Cabinet & base – Mount on a TB851/TB852 terminal base in a ventilated control cabinet; leave room for fiber bend radius.
• Wiring & fiber – Use the recommended ABB fiber type for DDCS; avoid tight bends and mixed connectors. Label channels for each drive.
• Grounding & EMI – Maintain proper cabinet grounding; separate power cabling from fibers and CEX-bus segments.
• Safety – De-energize the controller and observe ESD handling before inserting/removing the module.
• Routine checks – Inspect fiber connectors for dust, verify link status LEDs, and back up drive parameter sets periodically.
• Firmware & tools – Keep controller/engineering tools at recommended revisions; update during planned outages, not ad‑hoc.

Quality & Certifications

• CE compliant
• UL/cUL listed (typical for AC 800M modules)
• RoHS compliant
• Manufactured under ISO 9001 quality systems
• Warranty: 365 days (provided by us)

Related & Supporting Components

• TB851 / TB852 – Terminal bases for CEX-bus modules (mounting and power feed).
• PM864 / PM866 / PM861 – AC 800M CPUs commonly paired with CI858 for drive-centric applications.
• Fiber patch leads for DDCS – Use ABB-recommended fibers/connectors to maintain link quality.

One thing I appreciate is how the CI858K01 streamlines drive integration across a range of ABB drive families. If you’re upgrading from fieldbus gateways or facing EMI challenges, this module tends to be a straightforward win.
